In Plenilunio, Ldo Ivo speaks of abandonment and selflessness. His style is simple and without adornment, covering a vast array of subjects related to love and passion, life and death. It is also a meta-poetic book that speaks of poetry itself. The whys and hows of the world and of his own Brazilian society are explored, with the intention of showing us the way out of darkness and into an epiphany's light. This, to him, is his main role as a poet. "I want to be what fades away," Ivo says in these verses, "the soft white cloud that disappears in space, the reactor's smoke in a clear and empty sky."
